y2S Claims.

.This invention relates to lasting machines, and is herein illustratedas. embodied in Va machine for lasting with adhesive. .It is to beunderstood, however, `that Vfeatures of the invention vare not limitedto lasting with adhesive or to use in a machine .ci the exactconstruction herein disclosed.

vIt fis an object of Vthis invention .to provide a novel and improvedlasting .machine which is of relatively .simple :and inexpensiveconstruction, yet eiiicient .and `dependable .in operation. With thisend in View, and in accordance with -a feature of the invention, .theherein illustrated machine is provided withnovel and improved means fortensioni-ng the stock rto be :lasted comprising amember having anendless friction surface Ifor engaging one .side of the 'lasting .marginof the stock, and .movable in ya direction extending heightwise `of -ashoe presented to the machine, a second member for engaging ,the.opposite side ofsaid lastingimargin, andmeansfor periodically effectingrelative approaching movement of these members .to .cause the .frictionsurface vto exert a .-frictional .drag on the .lasting .margin therebyto tension .the stock .heightwise Tof the shoe.

.More particularly, the first-mentioned member consists oi an endless.exible element, e. g., a belt, having ia :friction .surface forengaging the outer .side .of vthe l-lasting vmargin of the stock,

while the `second mentioned member comprises n a lasting shield,associated with a .shoe-bottom rest, having .an operating surface `forengaging the inner side .of the .lasting margin and movable, with `theendless member, during the tensioning action. movements of thesemembers, an idler pulley is arranged .to vbear .against the endless`member and means are provided vfor V.causing this idler tpulley.periodically to move .the endless eX-ible `member toward the :lastingshield and into fric- 4tional engagement with thelasting .marginof .thestock.

In order to 'facilitate the lasting operation, and in accordance with afurther feature of the Vinvention, the `above-mentioned -noveltensioning means arearrangedaiso .to .effect aieeding of the shoe.Preferably, andas herein illustrated, this is .accomplished byYproviding means for moving .the endless flexible element, lastingshield and shoe-bottom rest, together and transversely of the directionin which .the stock is being tensiOned. At the completion of thesetensioning and feeding actions, the Vidler pulley is operated to `permitthe endless iiexible element to move away (from the lasting shield andthese members,

.For effecting the relative approaching d together with .the shoe-bottomrest, 'are moved reversely, i. e., back fed, to 'their originalpositions. This cycle of operations is repeated's'o that the stools istensione'd in different locations, su'ccessively, along the edge of thebottom of 'the shoe.

During the aforementioned back-'feeding'movement of .the .endlessflexible element, lasting shield and shoe-bottom rest, the shoe is heldagainst retrograde movement by'pressin'g means arranged to lay thelasting margin ci the .tensioned stock `down on and to press it against,the bottom of the shoe. This pressing means is operated .in 'timerelation 4to the 'tensioning and feedingaction, mentioned above, and,"in accordance with a'further feature of the invention, is adapted tomove toward the bottom of the 'shoe with a component of Amovementinwardly 'from the 'edge .of the shoe bottom. Preferably, and as hereinillustrated, the pressing means comprises a hammer that'is pivotallymounted on the end of a lever which is itself pivoted to an oscil latedoperating arm. The hammer is `yieldingly held in a position such that anOperating lface thereon is inclined to the 'bottom of .theshoe and thelever, on which the ,hammer is mounted, is yieldable relatively to theoperating arm. 'The arrangement is such that, as the operating .arm isoscillated, the .hammer firstengages thelasting l-margin of the .stockat the very edge of .the shoe bottom,.then pivots `on the end of thelever and swings down to `bear iiatly against the lasting vmargin -onthe shoe bottom, and nallyapplies pressure to the lastingmargin withiadefinite component of movement inwardly from the edge Lof the shoebottom, as the lever yieldingly pivots on the operating arm. Thiscombined .pressing and irl-wiping action of the hammerassures tig-htnessof the stock by avoiding any tendency of the pressing action alone toiloosenitaround the edge oi :the shoe bottom.

vThe above Yand `other 'features of the inven tion, including variousnovel details .of construc- 'tion and combinations of parts, will lnowbe more particularly described kwith reference vto the accompanyingdrawings and `thereafter Vpointed 1out in the claims.

Figs. 5 and 6 are views in side elevation, with certain parts insection, of other portions of the operating mechanisms in two differentpositions assumed during the operation of the machine.

Referring now to the drawings, the operative elements of the machineinclude a constantly running belt I0 for tensioning the stock to belasted, also operable to impart a feeding movement to the shoe, a hammerI2 for laying the lasting margin of the tensioned stock down on, and forpressing it against, the bottom of a shoe, a lasting shiel-d, orabutment, I4, for supporting the lasting margin of the stock as it isengaged by the belt, and an idler pulley I6 for moving the beltperiodically into engagement with the stock. During the operation of themachine, the shoe being lasted is supported by the operator and heldagainst upward movement, in response to the tensioning action of thebelt, by means of a bottom rest I8 associated with the aforementionedlasting shield I4. The belt I0, idler pulley I6, lasting shield I4 andthe shoe-bottom rest are all movable as a unit laterally of the machineto effect a feeding movement of the shoe. The hammer I2, which pressesthe lasting margin of the tensioned stock against the shoe bottom, isoperated in time relation to the action of the tensioning and feedinginstrumentalties, just mentioned, and operates to hold the shoe againstretrograde movement, while these instrumentalities are moved reversely,or back fed, to their original positions. During this back-feedingmovement, the idler pulley is shifted rearwardly of the machine topermit the belt to move away from the stock.

The operating elements are supported on, and operated by mechanismcontained within a head construction comprising a pair of verticallyextending side plates 20, 22, secured at their lower ends, by bolts 24,24 to a base member 28. This base member is mounted on the upper end ofa column 30 of a suitable height to b-ring the operating elements of themachine to the proper level for the operator. A treadle 32 is arrangedto be supported on the iioor by means of a bracket 34 and from thistreadle a treadle rod 36 extends upwardly through a bore 30 formed inthe base member 28, A compression spring 40, interposed between theupper surface of the base member 28 and a collar 42 on the treadle rod,ginds to hold the rod in the position shown in The belt I0, which may beformed of rubber, fabric or other suitable material, is of the wellknownV-type so as to present a flat friction surface II and is mounted on alower drive pulley 50 and an upper pulley 52, see Figs. 1 and 2. Thedrive pulley 50 is secured to a shaft 54 which is journaled in bearings56 and 58, carried by the plates 20 and 22 respectively. This shaftextends beyond the plate 22 and is provided with a power input pulley 60which is driven, from a motor, or other source of power (not shown), bymeans of a belt 62. The upper pulley 52 is formed integrally with twoface cams 64, 66 and a side cam 68 and this whole assemblage isrotatably mounted on a bushing 10, carried by a shaft 'l2 that isadjustably secured to the upper ends of the plates 20 and 22 by means ofclamp nuts 14, 14, see Fig. 1.

The idler pulley I6 is supported on an arm 80 which extends downwardlyfrom a bracket 82 that is rotatably mounted on a shaft 84 by means ofthree spaced and apertured ears 86, 08 and 80, see Fig. 4. Alsorotatably mounted on the shaft 84, and positioned between the ears 86and 88 of the bracket 82, is an upwardly extending arm 92 which carriesa cam roll 94 adapted to engage the cam 64, Figs. 2 and 3. The ears 86andV 88 of the bracket 82 extend rearwardly and support a boss 96 havinga bore 98 in which is positioned a plunger |00. This plunger is yield-`ingly urged against the arm 92 by means of a compression spring |02 thestrength of which may be varied by means of a threaded plug |04. Whenthe cam 64 is in the position shown in Fig. 2, the idler pulley I6 bearslightly against the inside face of the belt |0 and the spring |02 issubstantially relaxed. However, when the cam 64 assumes the positionshown in Fig. 3, the idler pulley I6 will be projected outwardli7 tomove the belt. toward the lasting shield I4, yieldingly through theaction of spring |02, and to the position shown. The lower end of thearm 92 is formed with a surface |06 against which a stop screw |08, inthe bracket 82, bears when the parts are in the positions shown in Fig-2. By adjusting the screw |08 the initial position of the pulley I 6with respect to the belt, Fig. 2, may be Varied.

The shaft 84 is journaled at one end in a bushing IIO, threaded into theplate 20 and held in place by means of a lock nut I|2, Fig. 4. On theother end of this shaft, a sleeve I I4, having an enlarged portionproviding a shoulder IIS, is secured, and this sleeve is journaled in abore I|8 in theplate 22. Also rotatably mounted on the shaft 84, betweenthe ear 90 of the bracket 82 and the sleeve I I4, is a lever |20, to theouter end of whichthe shoe-bottom rest I8 is adjustably secured by meansof a screw |22, and an arm |24, which is positioned adjacent to the ear88, of the bracket 82, and is separated from the ear of thisv bracket bya bushing |26. A compression spring |28, interposed between the bushingIIO and the ear 86, on the bracket 82- tends to hold the shaft 84,together with the bracket 82 and arms |20 and |24, to the right, Fig. 1,with the shoulder IIS on the sleeve ||4 against the plate 22. During theoperation of the machine, however, these parts are shifted to the left,toward the hammer I 2 and to the position shown in Fig. 4, periodically,by means of the cam 68 which acts through a lever |30'. This lever ispivotally mounted on the plate 22 by means of a block |32 and trunnionshaft |34 and has at one end a cam roll |36 for engaging the cam 68. Ascrew |38 is threaded through the other end of the lever |30 and isarranged to engage the end of the shaft 84. A lock nut I 40 is providedfor holding the screw I 38 in adjusted position.

On the inner end of the lever |20 there is a stud |50 which is embracedby a bifurcated end |52 on a lever |54, Figs. 2 and 3. This lever ispivoted to the plate 22 by means of a stud I 56 and is connected to thetreadle rod 36. When the treadle 32 is released and the rod 36 elevatedby the spring 40, the lever |54 is swung in a clockwise direction to theextent determined by a stop pin |58 on the plate 22. This movement ofthe lever |54 swings the lever I 20, in a counterclockwise direction andto the position shown in Fig. 2, and moves the shoe-bottom rest I8v andlasting shield I4 outwardly and -upw-ardlyaway from the belt I8: Whenthe parts are in this position, the outward movement of the belt; I8

bymeansof the cam 64 and idlerpulley I6 is notsuf'cient tQbring ,thefriction surface II of the belt into contact with the lasting shield I4.However, when the treadle is depressed, the `shoebottom rest |8 andlasting shield I4 will be swung downwardly and Aimvardly toward thebelt-and will assume the positions shown in 3 in which the swingingmovement of the lever |54 has been arrested by an eccentric Vstop |59which is mounted on the plate 22.` Now, when the belt I0 Vis movedoutwardly by the pulley i6 its friotion surface |v willcontact thelasting shield le, or the lasting margin of stock interposed between theshield I4 and the belt, e. g., the lasting marV gin of the cover C of aplatform shoe comprising an upper U and platform? assembled on alast L.Theshoe-bottom rest i8 which-bears against the platform P preventsupward movementof the shoe in response to the frictional drag nowimposed on the lasting margin of the cover C by the friction surface IIof the beltrlii, which is moving in the direction indicated by the arrowin Fig. 3. The lasting shield I4, which is pivotally mounted onV the endof the arm |24 and guided on the shoe-bottom rest by means of a pin |66and a slot |62, is, however, free to move upwardly. Thus, each time thebelt I8 is moved outwardly by the pulley I6, operated by the cam 64, itpresses the lasting margin of the cover against the shield I4 and thentensions it in a vertical direction, the lasting shield moving upwardlywith the stock during this tensioning action, see Fig. 3. Whenthe beltIn is withdrawn, as the cam 64 assumes the Yposition shown in Fig. 2,the frictional drag on the stool; ceases and the lasting shield isreturned to the position shown in Fig. 2 by the action of aspringpressed plunger |64, associated with the arm |24`and bearingagainst a surface |66 on the bracket 82, see Figs.l 5 and 6;

While the idler pulley I6 is in the position shown in Fig. 3 and thebelt Il) still exerting a frictional drag on the .lasting margin of thecover C, the cam 63 operates the lever |39v to shift the shaft 84,bracket 82, together with the idler pulley i8 and the arms |26rand |24,which carry the shoe.bottom restv I8 and the lasting shield lli,respectively, to the left and tothe positions shown in Fig. e, andthefshoe is moved along a corresponding distance. At, the compleN tionof this feeding movement of the shoe, the belt Il! moves away from thelasting shield and out of engagement with the lasting marginof thecover, cam 64 having now rotated from the position shownin Fig. 3 towardthat shown in Fig.V 2. The idler pulley i6, together with the belt I0,the lasting shield ifi and the shoe-bottom rest I8 are next movedreversely, i. e., back fed, by the action of the spring |28 that is nowpermitted by the cam 88 which has rotated away vfrom the position shownin Fig. 4, Thus these parts are returned, i. e., back fed, to theposition shown in Fig. 1. This cycle of tensioning and feeding actionsis repeatedso that successive portions of the lasting margin-of thecover C are brought into engagement with, and tensioned by,the fries.tion surface I I on the constantly running belt is,

At the completion of each feeding-action and just before the frictionalengagementvof the belt I0 with the lasting margin is terminated, by therearward movement of the belt as above explained, that portion ofAthelasting margin of the-tensioned-stock-justrbeyond the belt, i. e.,

6; to the left, Fig 4,- is -laid down on and .pressed firmlyzagainst theshoe bottom, i. e., platform P, bythe hammer I2. The lasting margin ofthe cover and/or -the bottom face of the platformv having beenApreviously treated with adhesive, this action of the hammer-|2 willcause the cover to be secured tothe platform. Thus, as the operationproceeds, successiveportions of the lasting margin `of the cover arefirst tensioned by the belt and then-laid down on and secured in lastedposition to the platform.

The hammer .|2-'ispivotally mounted on the outer end of a lever |18, bymeans of a pin |12 in the arm and an arcuate slot IM formed in a rib E16on the hammer, Figs. 2, 5 and 6. A -coil spring |18, connected at oneend to the arm |18 and at the otherv end to the hammer, tends to holdthe hammer yieldingly in the inclined position shown in Figs. 2 and 5.The lever |18 is pivotally mounted, by means of a stud |86, on an arm|82 which is itself pivotally mounted on a cross shaft |84 that issupported by the plates 2G, 22.` Also-pivotally mounted Von the stud I85| is a lugl.. The lever |18 has an end |88 which bears against aplunger |98 that is mounted in a thimble |92, threaded into the arm |82.A compression spring |94, in back of the plunger |98,.tends toswingvthe-lever in a clockwise di rection about the axis of the stud I 88 to theextent permitted .by the head of Va stop screw |96, threaded intorthearm I 82. A coil spring |98, stretched between the upper end of the arm|82 and a crossbar 200, carried by the plates 26, 2.2, holds the arm|82, yieldingly, in the position shown inl Fig.v 2 and with the head ofthe stud |88 against a-stop pin 202 that extends inwardly from the plate28.

The hammer is operated by oscillating the arm 82 about the axis of theshaft |84 and this action is effected by the cam 66 in the followingmanner. A lever 2li), having a cam roll 2l2 mounted `on its upper end,is pivotally supported on the plate 20 by means `of a stud 2M. At thelower end of this lever there is an operating nose 2|6 whichis adaptedto engage the end of the lug |86 ywhen thislug is swung upwardly to thepositionshown in Figs 5 and 6. A coil spring ZIB, connectedto the nose2'I6 and to 'the crossbar 288, tends `to hold the cam roll '2I2 againstthe cam 66 andthe `lever 2li) in the vposition shown in Fig.A 2; Forswinging the lug |85 up wardlyto bring its end into 'alinement with thenose 2|6- on the lever 2|9, a lever 22E) having a spring finger 222,`engaging the lug, is provided. This lever is pivotally mounted on acrossbar 22d, carried-'by the plates 20 and 212, and is provided with'abifurcated-end arranged to embrace the treadle rod 38. A collar 225 issecured to treadle rod 36v in a `position toswing the lever 228m acounterclockwise direction, and to the position shown in Figs. *5'and 6,when the treadle 3211s depressed, thus elevating the lug |86 so thatAits end is in front ofthe nose 2|6. When the treadle 32 isreleased,however, a coil spring 228, connected to the lever 228 and also to thecrossbar 208, returnsthe lever l22|) to the position shown inFig. 2,-detennined by a stop 238, and permits the lugalSS-.to swing downwardlyaway from the noseY 2|8, thus terminatingthe action of the hammer I2.

The action of thehammer I2 may best be understoodby-reference to Figs.2, 5 and 6 of the drawings. In Fig.` 2, the treadle 32 is released andthe lever 2|() now merely oscillates without the -nose2|6. engaging thelug |86 and the ham- .aaaaiacY mer I2 is, accordingly, idle. In Fig.' 5the hammer I2 is shown in a position assumed `at the beginning of itsaction and when the arm |82 has been swung inwardly by the cam 66 andlever 2li), the treadle now being ydepressed to elevate lug |86. Thehammer is now engaging the lasting margin of the cover C and is holdingit against the edge of the platform P. The end |88 of the lever |18,however, is still being held against the stop screw I 95 by the plunger|90 and the spring |94 and the hammer I2 is held in the inclinedposition shown by the Spring |18. Now, as the arm |82 is swung stillfurther toward the shoe, by the cam 66 and the lever 2|0, the hammer I2is moved to the position shown in Fig. 6 in which it lays the lastingmargin of the cover C down on and presses it against the bottom face ofthe platform P. As the hammer moves from the position shown in Fig. 5 tothat shown in Fig. 6, it first pivots on the end of lever il() so as tolie flatly on the bottom of the shoe. Then, as arm |82 continues toswing outwardly, the lever IIS turns on the stud |80, against theresistance of spring IM. As the `arm I 82 thus turns, the hammer movesinwardly from the edge of the shoe while still applying yieldingpressure to the lasting margin of the cover C. Thus the hammer has anappreciable component of movement inwardly from the edge of the bottomof the platform P so that, in addition to laying the lasting margin downand pressing it against the platform, the hammer also has a deniteinwiping action. This in-wiping action is very important since it tendsto draw the lasting margin inwardly from the edge of the bottom of theplatform and thus augments the tensioning action of the belt I8. Also,in the absence of such wiping action, the pressing action of the hammeralone might tend to loosen the cover C around the edge of the platformP.

In operating the machine, the shoe is presented thereto, by theoperator, bottom up and with the lasting margin of the stock to belasted, e. g., the cover C, inside of the lasting shield I2, with thetreadle released and the operating elements of the machine in thepositions shown in Fig. 2. As the treadle is depressed, the operatorholds the bottom of the shoe upwardly against the shoe-bottom rest I8land then permits the shoe to move inwardly, toward the belt Iii,

with the shoe-bottom rest and lasting shield. Immediately, thetensioning and feeding actions begin as the idle pulley I6 moves thebelt I8 outwardly to cause its friction surface to exert a frictionaldrag on the stock and the cam 68 operates to shift the belt I0, lastingshield I4 and shoe-bottom rest I8 in a direction to feed the shoe.Depression of the treadle also initiates the action of the hammer I2which lays the lasting margin of the cover C down on, and presses itagainst, the bottom of the shoe, i. e., the platform P, with anin-wiping action as described above. The operator merely supports andguides the shoe as the lasting operation proceeds. When the lastingoperation, which may be continued around the entire periphery of theshoe bottom, or along only a portion thereof, has been completed thetreadle is released and the shoe is removed from the machine.

While the herein illustrated machine is particularly adapted for, andhas been described as, performing the so-called cover-lasting operation,it will be understood that it is not limited to such use. On thecontrary, it is designed for, and capable of, performing a lastingoperation on conventional shoes wherein the lasting margin of the stock,i. e., the upper, is secured to a shoe-bottom member, i. e., aninsole,'with adhesive.
